This article exemplifies a theological hermeneutic where the concerns of systematic theology shape the way a NT text is read. It intends to show that the unfolding testimony of Acts 1–2 (1) continues the process begun in Luke 24 of moving its audience towardan incipiently triune portrait of Yahweh; (2) provides public testimony to the truth of God's lordship by narrating its embodiment in a restored Israel; (3) enlarges a trinitarian reader's imagination with regard to the nature of the triune life of God when that imagination is stimulated by Luke's portrait of the embodied risen and ascended Son.
